Abstract: 1,266,031. Bulked yarn; method of manufacture. D. C. EVANS (Monsanto Co.), 20 Jan., 1969, No. 3128/69. Headings D1F and D1W. A heat-set bulky thermoplastic filamentary yarn is characterised by crimps assuming a curve of sines, the apices of the crimps of the individual filaments being located in a haphazard relation with respect to each other, the filaments composing the yarn having been displaced laterally and interlocked one with another. The yarn is tested for sufficient intertangling by the following criteria; the yarn assumes a compact smooth non-bulky appearance under a longitudinally applied tension of 0.02-0.8 gm/denier without loss of interlocking filamentary coherency or bulkiness, but loses such coherency upon application of tension sufficient to strain the yarn beyond the nominal elastic limit thereof. The yarn preferably comprises at least two ends of untwisted or low twist drawn yarn, the filaments being of a multi-lobal form.  A method of producing the yarn described in Specification 1,266,032 comprises longitudinally forwarding untwisted or low twist drawn thermoplastic continuous filament yarn having latent bulkiness to and through a confined zone with an overfeed of at least 15%, directing a plurality of streams of heated fluid against the yarn in the zone, the streams having inlets to the zone closely spaced apart in staggered relation with respect to the direction of yarn travel and circumferentially arranged around the yarn path through the zone and collecting the yarn in a uniform manner. The heated fluid develops the latent bulkiness in the yarn and entangles the filaments. In a preferred embodiment, two ends of continuous filament yarn are taken from supply spools 1, 2 through guide 7 to draw roll 9 and associated cot roll 11. The yarn then passes round a heated snubbing pin 13 and to draw gear rollers 15, 16 which run at a faster peripheral speed than roll 9. The roller 16 is cooled by means of a jet 17. The crimped yarn is then overfed to a jet member 20 where the heated fluid streams intertangle the filaments and develop bulk. In a further embodiment, the gear-crimped yarn is packaged and then drawn from the packages when required for bulk development. The overfeed of yarn is in the range 15-60%, the fluid being steam at 160-235‹C moving at a mass velocity of 1.5-5.5 lbs/min/sq. in. of cross-section of the inlets to the zone. The jet member 20 comprises a shell 27 and an inner tube 28, the top of the inner tube communicating with a nozzle member 26. The nozzle member 26 has two frusto-conical bores interconnected at their small ends by a cylindrical bore defining an axial yarn path. Heated fluid is supplied to the shell 27 by means of inlet 33 and the fluid passes to the inside of tube 28 by means of ports 40 which communicate with the tube 28 by means of conduits which are closely spaced apart in staggered relation with respect to the axial path and are arranged circumferentially around the path.  The yarns are preferably formed from nylon or polyester filaments.
